Final answer:
The explosive use of TCP/IP can be attributed to the development of ARPANET, standardization of communication protocols, and the establishment of online service providers and commercial internet platforms in the 1980s and 1990s.
Step-by-step explanation:
The explosive use of TCP/IP can be attributed to several factors. Firstly, the development of the ARPANET network in the late 1960s connected government facilities and research universities, laying the foundation for the internet we know today. In the 1980s, the standardization of communication protocols and the emergence of the World Wide Web further fueled the growth of TCP/IP. Additionally, the advent of online service providers and the establishment of the first commercial internet platforms in the 1990s expanded access to the internet, leading to its widespread use.
